cysts/potato

Nematode community structure of the potato fields with different infection levels of potato cyst-forming nematode (PCN) such as 10, 30 and 214 cysts per 100 g of soil has been investigated. The influence of specialized parasite on nematode fauna and dominance character of different

The potato cyst nematode (Globodera rostochiensis cv. Woll) is responsible for large yield losses in the potato crop, and opportunities for reducing the attack of these plant nematode species are, therefore, important. This study has been devoted to the testing of the in vitro effects on the potato

Potato cyst nematode poses a significant threat to potato producers in the Czech Republic. Both species of potato cyst nematodes (Globodera rostochiensis and G. pallida) are listed as quarantine pests in the Czech Republic and also by the European Union, European and Mediterranean Plant Protection

Potato cyst nematode, Globodera pallida, was detected in several soil samples collected from various areas of the Czech Republic. Globodera rostochiensis pathotype Ro1 is known to be widespread in the Czech Republic. G. pallida was reported from the neighboring countries of Austria, Germany, and

ABSTRACT Infestation foci of potato cyst nematodes (Globodera rostochiensis and G. pallida) in the provinces of Zeeland, Friesland, Groningen, and Drente of the Netherlands were sampled to validate a model describing infestation foci based on data from Flevoland. Eighty-two fields were presampled to

AFLP was used to characterize 24 potato cyst nematode populations. This novel DNA fingerprinting technique enabled the identification of 987 marker loci by screening only 12 primer combinations. Data on presence or absence polymorphisms and data on the intensities of corresponding DNA fragments were

Secretions were induced from second (invasive) stage juveniles (J2s) of the potato cyst nematode Globodera rostochiensis by exposing them to 5-methoxy-N,N-dimethyl tryptamine oxalate (DMT). Secretions were collected from J2s in sufficient quantity to allow direct analysis. Gel electrophoresis

The expression of host genomes is modified locally by root endoparasitic nematode secretions to induce the development of complex cellular structures referred as feeding sites. In compatible interactions, the feeding sites provide the environment and nutrients for the completion of the nematode's

A series of lignans fromBupleurum salicifolium Soland (Umbelliferae) were tested for nematostatic activity on the cysts and freed secondstage juveniles of the potato cyst nematodesGlobodera rostochiensis andG. pallida. None of the six lignans tested-bursehernin, matairesinol, syringaresinol, the

Potato cyst nematodes are a significant threat to potato production worldwide and have important economic impacts due to yield losses but also because of the expenses associated with regulation procedures. In order to reduce the sampling labor, an alternative strategy named the "Piler

Potato cyst nematodes (PCN), the golden cyst nematode Globodera rostochiensis (Woll.) Bahrens, and the pale potato cyst nematode G. pallida (Stone) stand out by their remarkable and efficient parasitic adaptations causing high economic losses in potato production worldwide. They are A2 quarantine

ABSTRACT In preparasitic second-stage juveniles (J(2)) of potato cyst nematode Globodera rostochiensis, six proteins with molecular masses of 30, 31a/b, 32, 39, and 49 kDa were recognized on Western blots by a monoclonal antibody (MGR48) specific for the subventral esophageal glands. All of these

The potato cyst nematode, Globodera pallida, is a globally regulated potato pest. Detected in the U.S. in the state of Idaho in 2006, the infestation, as of February 2019, is limited to 1,326 hectares. Globodera pallida is an obligate sedentary endoparasite that reduces yields up to

Seven filamentous fungal species were isolated from individual eggs of Globodera pallida cysts collected from infested fields in Shelley Idaho, USA and identified as Chaetomium globosum, Fusarium oxysporum, Fusarium solani, Fusarium tricinctum, Microdochium bolleyi, Purpureocillium lilacinum, and

The effect of the nematicide cadusafos on the hatching of the potato cyst nematode Globodera pallida in potato root diffusate, soil leachate, and distilled water was investigated. Cadusafos had a significant effect on the hatching, migration, movement, and root invasion by the second-stage
